To all whom it may concern.-

Be it known that I, RUDoLF REITHOFFER, a subject of the Emperor ofAusaria-Hungary, residing at Rudolfsheim, near Vienna, in the Provinceof Lower Austria, in the Empire of Austria-Hungary, have inventedcertain new and useful Improvements in Egg-Boilers, (for which I haveobtained Letters Patent in the following countries: in Austria- Hungary,dated December 20, 1888, No. 36,093 and No. 55,722; in Germany, datedAugust 3, 1888, No. $6,796; in France, dated August 3, 1888, No.192,209; in Italy, dated September 30, 1888, Reg. Gen. Vol. XXII, No.23,926, Reg. Att. Vol. XLVII, No. 218; in Sweden, dated August 3, 1888,No. 1,717, and in Norway, dated August 4, 1888, No. 1,012 and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit ap-' pertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Referring to the drawings, Figure 1 is a seetional elevation of myimproved egg-boiler, showing the parts in their operative position. Fig.2 is a like view showing the parts in their relative position after theboiler has completed its downward motion, the boilercover, theegg-carrier supports, the time mechanism and its support, and otherparts being omitted. Fig. 3 is a rear elevation of the clock-casing,showing the releasing and. alarm mechanisms and devices.

The invention relates to egg-boilers, and has for its object to providemeans whereby the eggs are automatically removed from the boiler afterhaving remained in the boiling water for a predetermined time.

To these ends the invention consists in the combination, with a fixedegg-carrier, of a movable boiler and a heating device for said boiler;in the combination, with the movable boiler and heating device, of anextinguisher for automatically extinguishing the heaterfiame; in thecombination, with the boiler, of a time mechanism, a locking device forlook ing the boiler against movement, and a reneeted to a short sleeve,0

leasing mechanism controlled by the time mechanism to release theboiler, and in certain structural features and combinations of elements,substantially as hereinafter described, and as set forth in the claims.

In the drawings, A indicates a base-plate or support, to which aresecured three standards, B B and If. The standard 7L3 carries the timemechanism, hereinafter to be described, and the standards B B carry theegg-carrier. The standards B are preferably hollow, so that theegg-carrier may be removably connected therewith.

The egg-carrier consists, first, of a support-= ing-yoke, C, comprisingthe arms 0 0 the outer or free end of which is bent to form a loop oreye, 0 while the inner ends are con- Headed pins 0, passing through theeyes 0 and into the standards B, serve to connect the yoke with thestandards, thus providing a stationary support for the egg-carrier.

The egg-carrier proper consists of a tube, cl, that has secured theretoa plurality of egg rings or loops, D, or is provided with a disksuitably perforated for the reception of the eggs, and said tube issupported at its lower end by the short sleeve 0 of the yoke O. In theupper end of the tube (Z is seated a handle, G, to which a cover issecured that has a suitably-slotted flange to fit over the arms 0 of theyoke O to close the boiler E when in its operative position, as shown inFig. 1.

WVithin the tube d is fitted a second tube, c, that has a spiral slot, 0formed therein the whole length thereof, said slotted tube projectingslightly below the short sleeve c", with which it is rigidly connected.In the slotted tube 0' is fitted a spindle, e, that is provided with apin, 6, projecting into the slot 0 of tube 0, and the lower end of saidspindle c is rigidly secured to the bottom of the boiler E, which ispreferably a cylindrical vessel of sheet metal. The upper and lowerterminals of the slot 0 limit the vertical move ment of the boiler andits spindle within the tube 0.

As shown at E, a portion of the bottom of the boiler is made to projectand has its edges made flaring, such portion acting as a deflector forthe flame of a lamp, F, so as to more uniformly distribute the heat overthe boiler-bottom, to which is also secured an extinguisher-cup, e,tl1at fits over the wick-tube of the lamp.

The lamp F is preferably supplied with alcohol, and may have 'acylindrical or flat wick tulr e, f The fount itself may also be ofcylindrical and preferably of slightly tapering form, and is supportedin an elevated position by means of a spiral spring, f, arranged in asectional telescopic casing or housing, F composed, as shown, of twosections, f f

It will be observed that v by providing a spiral slot and imparting acompound rotary vertical motion to the boiler the locking device for thelatter need not be as strong as it would have to be when the boilerhas asimple rectilinear motion, for the reason that the full weight of theboiler does not bear upon such locking device. In fact, but a veryslight resistance to the motion of the boiler will hold it in position,so that no powerful mechanical device need be employed to release saidboiler. I am thus enabled to employ a time mechanism of a compact form.and simple in construction, which I will now describe. The timemechanism comprises a power-spring and a main arbor, 72. which carriesor which may be revolved by a windingkey, h, to wind up thepower-spring, said arbor carrying also a hand, 7L7.

In combination with the spring and arbor I employ a minute-train ofgearing controlled by an escapement and a pendulum, h, which train ofgearing, escapement, and powerspring I have deemed unnecessary to show,as such are well known, though I would remark that the hand-arbor a isrevolved by the spring and minute-gear in a direction the reverse ofthat in which it revolves when winding up the spring, so that the hand71 will always indicate the time to which the mechanism isset and whenthe winding up is to be stopped. For instance, as shown in Fig. 1, thearbor it has been rotated to wind up the springuntil the hand reachedthe threeminute indicator. The winding up having then ceased, the boilerwill be released, when the hand returns to 0, the time mechanism beinglimited to ten minutes in the example given, which is more than amplefor boiling eggs to any desired degree.

The devices for locking the boiler against motion and for automaticallyreleasing the same consist of a radial arm, 6 secured to the boiler, anda stop arm, h, pivoted to the back frame-plate of the clock mechanismand projecting through the clock-casing H into the path of the radialarm 6 which, when the boiler is in its most elevated position, bearsagainst said stop-arm h, as shown. It further consists of a disk, hsecured to the main arbor 71/, said disk being provided with alifter-pin,

* 7L2, in the path of the stop-arm h, which lifts the latter out of theway of the radial arm a On said disk h is also pivoted a pawl, h thatoperates a-tripping-arm on the bell-hammer pivot to lift the hammer Hagainst the stress of its spring h and strike the bell B, thus soundingan alarm simultaneously with the release of the boiler, h being theabutment-pin for the pawl to hold it in position.

The operation of my improved boiler is as follows: The parts being intheir relative positions, (shown in Fig. 1,) the clock is wound up tobring the hand to the three-minute indicationthat is to say, the arbor hhas been rotated from right to left, or. in the direction of the arrow,until the hand starting from zero or 10 reaches the index 3, and thenstopped. The boiler will now remain in the position shown for nearlythree minutes, when, the releasing devices being in about the positionshown in Fig. 3, a further movement of disk 7?. will lift the arm h outof contact with the arm e and the pawl It will trip the hammer to soundthe alarm, while the hand M will have traveled backward to zero. Theboiler under its own weight will now revolve and descend, theextinguishencup will extinguish the flame of the lamp F, which under theweight of the boiler will be forced into the housing F, and said housingwill be telescoped. Inasmuch as the egg-carrier is stationary, the eggswill be automatically removed from the boiling water, as shown in Fig.2. The cover G during the downward motion of the boiler will also remainin its position, being supported by the carrier-tube d and thecarrier-yoke C. The radial arm a also serves as a handle to move theboiler into the position shown in Fig. 1.

The advantages of my improved egg-boiler will be readily understood.

Having described my invention, what I claim is r 1. An egg-boilercomposed, essentially, of

socketed supports, an egg-carrier provided with arms terminating in aneye, and locking-pins adapted to pass through said eye and fitting intothe sockets of the supports, in combination with a boiler adapted tomove in the plane of the carrier, said carrier being constructed to fitinto said boiler, substantially as and for the purposes specified.
